* Don't compile non-lib modules as lib modules [BZ #21864]H.J. Lu2017-08-214-1/+5
| | | | | | | | | | | | | Some programs have more than one source files. These non-lib modules should not be compiled with -DMODULE_NAME=libc. This patch puts these non-lib modules in $(others-extras) and adds $(others-extras) to all-nonlib. [BZ #21864] * Makerules (all-nonlib): Add $(others-extras). * catgets/Makefile (others-extras): New. * elf/Makefile (others-extras): Likewise. * nss/Makefile (others-extras): Likewise.
* Mark __libc_multiple_libcs with attribute_hidden [BZ #18822]H.J. Lu2017-08-216-8/+17
| | | | | | | | | | | | | | | Since __libc_multiple_libcs is defined as hidden symbol in init-first.c, it should be always marked with attribute_hidden.

| | | | | | | | | | | | | | | | | The logic to define isinf for float128 depends on the availability of __builtin_types_compatible_p, which is only available in C mode, however, the conditionals do not check for C or C++ mode. This lead to an error in libstdc++ configure, as reported by bug 21930. This patch adds a conditional for C mode in the definition of isinf for float128. No definition is provided in C++ mode, since libstdc++ headers undefine isinf. Tested for powerpc64le (glibc test suite and libstdc++-v3 configure). [BZ #21930] * math/math.h (isinf): Check if in C or C++ mode before using __builtin_types_compatible_p, since this is a C mode feature.

* Add math benchmark latency testWilco Dijkstra2017-08-173-10/+43
| | | | | | | | | | | | | | | | | | | | | | This patch further improves math function benchmarking by adding a latency test in addition to throughput. This enables more accurate comparisons of the math functions. The latency test works by creating a dependency on the previous iteration: func_res = F (func_res * zero + input[i]). The multiply by zero avoids changing the input. It reports reciprocal throughput and latency in nanoseconds (depending on the timing header used) and max/min throughput in iterations per second: "workload-spec2006.wrf": { "reciprocal-throughput": 100, "latency": 200, "max-throughput": 1.0e+07, "min-throughput": 5.0e+06 } * benchtests/bench-skeleton.c (main): Add support for latency benchmarking. * benchtests/scripts/bench.py: Add support for latency benchmarking.

* Fix sigval namespace (bug 21944).Joseph Myers2017-08-1610-20/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XPG4.2 defines the siginfo_t type, but not union sigval or its contents (which were added in the 1993 edition of POSIX.1), resulting in namespace violations for sigval, sival_int and sival_ptr for signal.h and sys/wait.h for that standard because those headers incorrectly expose those names in that case. This patch fixes this problem. The public type in this case is union sigval, but various places in the headers use the sigval_t name for it; direct uses of union sigval are already properly guarded or in headers not in XPG4.2. Now, sigval_t, although not a standard name, does seem to be widely used outside glibc. The approach taken by this patch is to make installed headers use the name __sigval_t instead. __sigval_t is then defined to either union sigval or union __sigval (where union __sigval has __-prefixed member names as well), depending on whether there are any namespace issues with the union sigval name and its members. In the case where union __sigval is used, sigval_t is not defined at all, to avoid the problem of sigval_t having a C++ mangled name that depends on feature test macros. sigval_t is still defined by signal.h if __USE_MISC (reflecting the nonstandard nature of that name). Tested for x86_64. [BZ #21944] * signal/bits/types/__sigval_t.h: New file. * signal/Makefile (headers): Add bits/types/__sigval_t.h. * signal/bits/types/sigval_t.h: Include <bits/types/__sigval_t.h> and define sigval_t using __sigval_t. * include/bits/types/__sigval_t.h: New file. * bits/types/sigevent_t.h: Include <bits/types/__sigval_t.h> instead of <bits/types/__sigval_t.h>.

* Allow abort PLT references in libc.so for SH.Joseph Myers2017-08-162-0/+7
| | | | | | | | | | | | | | | | | | | | | | Given my patch <https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00965.html> for the ICEs building a glibc string function test for SH, the testsuite can build completely for SH with GCC 7 and mainline. However, there is a test failure that does not appear for GCC 6: check-localplt fails because of an abort PLT reference in libc.so. Given the lack of a trap insn pattern for SH, it seems unavoidable that the compiler might sometimes generate abort calls, and such abort calls (generated from __builtin_trap when there is no trap insn pattern) will be unaffected by the normal mapping to __GI_abort for calls within glibc. Thus, this patch allows (but does not require) an abort PLT reference in libc.so for SH. Tested for sh4-linux-gnu with build-many-glibcs.py (GCC 7, with my patch applied). * sysdeps/unix/sysv/linux/sh/localplt.data: Allow abort in libc.so.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 384ca551743318bd9c9e24a496d6397f2e3f2a49 from 2007 added this to nss/XXX-lookup.c: +#ifndef NO_COMPAT +int +internal_function attribute_compat_text_section +DB_COMPAT_FCT (service_user **ni, const char *fct_name, void **fctp) +{ + return DB_LOOKUP_FCT (ni, fct_name, NULL, fctp); +} +#endif That is, it adds a pseudo-compat function with an internal_function attribute. The function it was supposed to replace did not have the attribute: extern int DB_LOOKUP_FCT (service_user **ni, const char *fct_name, - void **fctp) internal_function; + const char *fct2_name, void **fctp) + internal_function; This changed the calling convention on i386 for the following functions in the public ABI: __nss_passwd_lookup __nss_group_lookup __nss_hosts_lookup This commit replaces the functions with always-failing stubs, with true compat symbols. Due to a happy accident, the calling convention of the stub is identical for the internal_function and non-internal_function case on i386. In addition, this commit auto-generates the __nss_*_lookup2 function declarations as part of <nsswitch.h>.
